It looks like packages that build-depend on tex* will simply not build
on Emdebian Grip - for (of all things) legal reasons - without pulling
the unchanged Debian packages. It means bringing in the massive
Packages.gz file from Debian but then, the texlive dependencies aren't
exactly small.
Probably the easiest way to do that is simply remove tex* packages from
Emdebian Grip unconditionally. (Grip is filtered, we can easily prevent
Debian packages being included into Grip.)
Are there other packages anyone knows about that prevent the removal
of /usr/share/doc/foo by some automated process for legal reasons?

That means downloading the docfiles in the first place which is what we
avoid by using Emdebian Grip. If the unchanged package needs to be
downloaded, it's not that much of a gain over having the package from
Debian unchanged, which is what it sounds like we would have to do.

Emdebian Grip drops Recommends so the problem goes away entirely - at
least it would if the resulting package was legal and would work as a
build dependency.
